When turning on or resetting the game, hold down Y, X, R, and Start on controller 2 until the Riot logo fades out. If this is done successfully, selecting either Start or Continue at the title screen will cause the chapter select menu to appear. Press Up/Down on the D-Pad to select a starting chapter and Y to begin the game.
Using the chapter select menu will also make two hexadecimal numbers appear in the corner of the screen. The first two digits represent the screen brightness (0F is the maximum,) while the second two digits are the current stage number, corresponding to the numbers in parentheses on the chapter select menu.
The following additional controls are also available after using the chapter select menu:
- Hold L to freeze the game and press R to advance one frame at a time.
- Press Select to cycle through available weapon levels.
